You don't have to have an mRNA vaccine. You can have one containing an unactivated virus just like the vaccines of old that nobody seemed to be afraid of.
Well the Covid vaccines have been fully tested and haven’t skipped any trial stages so are you suggesting that the Polio vaccine did? https://mobile.reuters.com/article/amp/idUSL1N2M70MW
Not possible I’m afraid Des. Unless you have information that I’ve never seen, the virus has never been isolated so it’s totally impossible to take a piece of the virus and use it as you would to create a vaccine as was done with the previous tried and tested vaccines.
